INKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 652,113, dated June 19,1900. Application filed September 8. 1899- Serial No. 729,798. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, HERBERT H. J ACOBUS, a

citizen of the United States, residing in Cedar e an improved apparatusof this class by means of which ink may be transferred from a suitablesupply-fountain and thoroughly and uniformly distributed over all of therollers of the inking apparatus and to facilitate the transfer of theink from the receiving-roller to the more remote rollers of the inkingapparatus.

In order to obtain the above results, I make use of an inking apparatusmade up of a main inking device and a second inking device carried onthe main one and movable relatively thereto, this second inking devicebeing preferably so constructed that one of its inkingrollers willalways be in contact with one of the rollers on the main inking deviceand yet will have a movement other than the ordinary movement ofrotation which serves to permit the transfer of the ink from the oneroller to the other. In the present case both the main and the secondinking devices are oscillatory, the second one being mounted foroscillation as a whole on the main inking device during the time whenthe latter has no movement as a whole. One of the rollers of this secondinking device serves as a transfer-roller for taking the ink from theordinary transfer-roller in contact with a doctor-roll attheink-fountain, and this transfer-roll on the second inking device maynot only serve to lead the ink-film onto the other rollers of theseries, but may also be employed to apply ink directly to the printingcylinder or form with which the inking apparatus cooperates.

Other novel features of this inking apparatus not heretoforespecifically referred to will be pointed out in the specification andare clearly shown in the accompanying drawings, in which Figure 1 is aside elevation of one end of a printiug-machine embodying an inkingapparatus constructed in accordance with my present invention. Fig. 2 isa similar view of a portion of the same, illustrating the inkingapparatus and its coacting devices in detail, parts being broken away inorder to illustrate more clearly the construction. Fig. 3 is a sectionalplan of the same brokenin the center. Fig. 4 is an enlarged transversesection of the ink-fountain and the inking-rollers, illustrating oneposition of the latter for feeding ink; and Fig. 5 is a similar viewillustrating another position of such rollers.

Similar characters of reference designate like parts in all the figuresof the :drawings.

My improved inking apparatus may be employed in connection with anysuitable print-' ing-machine-such, for instance, as that of which oneend is shown in the drawings. In this case the supporting-frameworkembodies two heavy side frames or castings, such as A A, suitablyconnected and supporting at the left-hand end the material to beprinted,which will usually be carried in the form of alarge roll, suchas R, suitably supported for rotation, as by a shaft 2. From this roll Rthe paper is fed by any suitable feeding mechanism (not shown) between apair of impression members or printing-cylinders, the lower one of whichmay be carried on a shaft preferably driven by a pinion on the maindrivin'g-shaftlO of the printing-machine. The pinion 10' on the shaft 10will in this case drive the lower impression-cylinder 0 directly throughthe medium of a large spur-gear 51, carried by a shaft 52, suitablyjournaled in the side frames A A, and the movement of the gear 51 willbe transmitted to a gear 53 of the same size on one part of a rotarymember or shaft S, which will preferably be mounted in such a manner asto be capable of adjustment toward and from the shaft 52 in order thatthe surfaces of the two printing-cylinders O and 0 may be shifted towardor from each other to control the impression or inspect the work. Inaddition to this it is also desirable that the upper cylinder 0, whichin this case is the main or printing cylinder proper, should be capableof removal from the machine readily in order to permit the insertion ofa cylinder without disturbing the remainder of the mechanism.

A A, so that when the ink is deposited by the transfer-roll onto theform-roller it is also simultaneously drawn thereon and in this fountainreciprocates.

manner distributed so as to cover the surface of the form-rollerlongitudinally thereof, a feature which is ,of especial advantage innewspaper-work, where the cheaper inks are used and where theductor-scrapers must be frequently adjusted to prevent lumping on theform-roller. The connection between the fountain and the cross-beam maybe made in any suitable way; but I prefer to mount said fountain on adovetailed guide, such as 91, bolted to the cross-beam in such a manneras to be removable therefrom toward the right-hand side, as seen in Fig.3. On this dovetailed guide 91 the fountain may reciprocate endwise, ithaving in this case a cooperating dovetailed guideway 92 in its underside. This ink-fountain supports therein the usual ductor-roll 93, and atransfer-roll 9st is journaled in the ends of a pair of links 95 and 96,pivoted to opposite sides of the fountain. This transfer-roll will makecontact alternately with the ductor-roll and with another way by 10,)the ratchet-wheel being secured to a short shaft; 97, journaled in asuitable bearing and having at its opposite end a squared longitudinalbore, such as 97, in which a correspondingly-squared end 90' of thedoctor-roll shaft 98 may slide as the ink- The link 100, by which motionis communicated to the pawland-ratchet connection 9, may be connected bya suitable spring-pressedrod, such as 101, to the shaft 12 and suitablyoperated by a cam or wiper thereon, the spring serving to return theparts to their normal positions.

The reciprocatory movement of the inkfountain may be obtained in anysuitable manner; but in this instance a large spurgear 102 on the shaftS has on one side thereof a circuit of projections and depressionsforming a crown-cam, (designated herein by 103,)

with which cooperates an antifriction-roll on the end of a lever 104,carried by a shaft 105, suitably journaled in the framework. At-itsupper end this lever 104: may be connected by a link, such as 105,directly to the ink- (sane fountain to shift the same in one direction,a suitable spring, such as 106, being employed to effect the returnmovement of said fountain. Another lever-arm, such as that shown at 107,formed substantially as a shippinglever, may be secured to the shaft 105and may serve to impart a reciprocatory movement to one of'theinking-rollers which cooperates with the printing-cylinder.

In order to permit access to the cylinder 0, especially in removing thelatter, I prefer to employ an inking device shiftable toward and awayfrom said cylinder, and the main inking device, which is indicated in ageneral way by I, may be supported for oscillation on the bearings ofthe shaft 52. This main inking device will usually embody a pair of sideframes or rock-arms, such as 110, which may be connected by a rod 112,and the main inking-frame may be secured in its working position by alatch and a detent, such as 113 and 114.

Any desired number of inking-rollers may be supported on the rock-arms110, andthey may be mounted in any desired manner; but I prefer tosupport thereon two shafts, such as 115 and 116, carrying inking-rollers117 and 118, these shafts being geared directly to the spur-gear 102 bypinions 119 and 120. The shafts 115 and 116 are not in this case,however, journaled directly in the rock-arms 110, but are preferablycarried at their opposite ends by yielding bearings, all of which are ofthe same construction. By referring to Figs. 2 and 3 it will be seenthat these shafts are j ournaled directly in spring-pressed bearings,such as 125, suitably guided in the rock-arms 110, and that the bearingsin the latter are open at their upper sides in order to permit theshafts to be removed readily with their yielding bearings. A thirdfrictionally-driven ink-roller, such as 130, in contact with theink-rollers 117 and 118, is carried by a shaft 131 intransversely-elongated bearings in the rock-arms 110.

In addition to the parts just described the main inking device willpreferably carry a second inking device supported thereon foroscillation relatively thereto, and in this case the shaft 116 may formthe support for the second inking device, this latter having oscillatoryside plates or links, such as 135, connected, as by the shafts of theinkingrollers, to form a suitable frame, said side plates or linkshaving proper bearings for ink-roller shafts. Here two of these shaftsare journaled directly in such side plates, said shafts being designatedby 136 and 137 and carrying corresponding ink-rollers 138 and 139. Theshaft 136 may be supported for reciprocation in its bearings and may bereciprocated by the lever 107, hereinbefore mentioned. (SeeFig.3;)Moreover, thebearings for this shaft may also be transversely elongated,as are those of the shaft 131.

The ink-roller 138 is frictionally driven by contact with theink-rollers 118 and 139, the

sta ns e latter of which oscillates with the second inking device '5toward and from the surface of the printing-cylinder. WVhen in itsraised or receiving position, this inking roller 139, which ispractically driven from the printing-cylinder, will receive ink from thetrans fer-roll 9 1 when the latteris traveling bodily with theink-fountain during its reciprocation on the ways 29, and since theroller 94 is when in its raised position out of contact with thefountain-roller 93 and in contact with the rotating form-roller 139 inkwill be deposited and drawn on the latter at different points of itssurface and spread by the roller 138. It will thus be seen that the inkon the roller 139 is distributed thereon to some extent preparatory tothe descent and subsequent contact thereof with the form on the cylinderand that a comparatively great amount of ink is deposited on the form tobe spread thereon by the rollers 118 and 117 as the form comes intocontact with the same. When the roller 139 is in its inking position, asshown in Fig. 5, the transfer roll 94 is entirely clear of the same andin contact with the fountain-roll to receive a fresh supply therefrom.

The oscillatory movements of the device 2' may be obtained in anysuitable manner as, for example, from a rod 140 engaging, but notconnected to, some suitable portion of said device 2', this rodbeingpreferably guided at its upper end, while the lower end thereof maybe operated from the shaft 12 by a cam on the latter, the weight of theinking device serving to impart the return stroke to the rod 140.

In order to limit the movement of the inking device '5 relatively to themain device I, the latter may have thereon a fixed stop 145 in positionto engage some suitable member of the device 1' when the main and secondinking devices are thrown back to the position shown in dotted lines inFig. 2.

The bottom plate or ductor of the inkfountain, which plate is indicatedherein by 150, may be adjusted at its feed end rela tively to theductor-roll by suitable adjusting-screws, such as 151, in order tocontrol the thickness of the ink-film led off by the ductor-roll.

The operation of my improved inking apparatus may be briefly stated asfollows, viz: Ductor-roll 93 is intermittingly turned by the connectionsdescribed, and the periphery thereof takes up ink from the fountain F.\Vhen rollers 117, 118, and 139 are'in contact with the printing rolleror cylinder 0, as shown in Fig. 5, the transfer-roll 94 is free fromcontact with roll 139 and its periphery is in engagement with that ofthe ductor-roll 93 and receives a layer or coating of ink therefrom, andthis ink is transferred to and spread upon the roll 139 when said rollis thrown into contact with the transfer-roll 94:, as shown in Fig. 4,and from the roll 139 it is conveyed to the inking-roller 118 byintermediate roll 138 and from said roll 118 to inking-roll 117 by theintermediate roller 130. In this way all of the form or inking rolls areproperly and evenly coated with ink in order that the same may betransferred to the form upon the cylinder which rotates beneath them.

Should it be desired at any time to expose the cylinder carrying theform for any purpose, latch 113 is released from catch 114: and the arms110, in which the inking-rollers are j 0urnaled,are swung to theposition shown by dotted lines in Fig. 2.

By reciprocating rolls 91 and 138 in the manner described the ink isevenly distributed upon the rollers 118 and 139, and is consequently inthe proper condition to be applied to the form.
